| IRC's Open Air Resistors |
Thursday, May 29, 2008
LAS VEGAS, NV (May 6, 2008) -- Developed specifically to
provide a current sense device with high current-carrying capability
for power electronics circuits, the OARS-XP Series metal element
resistors from TT electronics IRC deliver power ratings up to 5
watts in a unique, flameproof open-air surface mount form factor
that offers the maximum heat dissipation for a PC board mounted
component.
The OARS-XP Series resistors consist of a 0.25" wide metal
element resistance alloy, welded to compliant copper terminals
designed to handle TCE (thermal coefficient of expansion) mismatch
between the device and the PC board. Unlike other resistor
technologies, such as thin film, thick film or foil devices, the open
air metal element will not experience degradation of performance
at extreme temperatures, even up to 500°C (a conservative
temperature rating for the alloy itself). However, since most
PCB solder materials typically melt between 183°C and 230°C,
the solder will reflow long before the device itself experiences
any heat damage.
Applications for the OARS-XP Series resistors include surge
and pulse circuits, AC power applications, and current sensing
and feedback circuits.
Resistance value for the resistor ranges from 1mohm to 25mohms
(.001ohm to .0025ohms), with tolerances down to ±1%. Inductance
values are less than 10 nanohenries, with operating temperature
ranging from -40°C to +125°C. IRC will also produce devices outside
these specifications to meet customer requirements. Lead-free
RoHS-compliant and zero ohm jumper versions are also
available.
Typical pricing for OARS-XP Series resistors is $0.53 each in
quantities of 10,000 pieces. Lead time is from stock to 10 weeks.
